I am developing an application for my fan page, everything works fine, but I can’t install it on a fan-only page. Do you need to install a fan page?
https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&display=popup&next=YOUR_URL
YOUR_URL should be the URL of the page of the page from the application settings.
http://www.facebook.com/add.php?api_key=YOUR_API_KEY&pages
Replace YOUR_API_KEY with your application key, and then choose which FanPage you want to install.
Go to https://developers.facebook.com
Select the application you want to use
on the "Settings" tab, scroll down and click "Add Platform", there you can select the "Tab" Page ", after which you will be presented with a configuration screen
Get your app ID then go to http://facebook.com/APP_ID
which will show your APP profile page.
On the left side you need to click
Add to my page
you will see all your own facebook pages, just select the one you want
